Asparragus

Description

Asparagus is a plant with a claw-shaped rhizome, which is complemented by thick roots that accumulate nutrients and fine roots that absorb water and nutrients from the soil. The stems or shoots that grow from the rhizome are the organs that are harnessed, before the stem leaves unfold. If the stem develops under the ground without contact with light, it appears white. On the contrary, if this stem grows outside, it will be green.

In Spain, asparagus production is between 70,000 tons, occupying up to 15,000 hectares in the provinces of Seville, Cáceres and Navarra. Part of this production is exported and another part is transformed for industrial consumption (approximately 20%).
